Please help me with another question thanks!

Question 4 (15 marks) A laboratory test on a concrete sample has measured the variation of the compressive strength, fck, with the curing time, t. Data are reported in Table 1. Table 1 Data of the laboratory test for Question 4 |||) Curing time [day] 1 2 5 7 18 28 50 Compressive Strength (MPa) 1 3 5 18 24 26 32 (0) Given the model fck = a1 + a2 loget, determine the coefficients az and a2. (6 marks) Copy and paste your MATLAB code below: Determine the value of the compressive strength at t=38 days by using the obtained formula, paste your result below: (4 marks) Plot below a figure showing both experimental data in Table 1 (scatter plot) and model curve (continuous curve)
